Its circuit choices and project progress are documented there.++## Z-up display model++The interactive 3D view uses `DSE0006A.adom-zup.glb`, a separately named orientation derivative. The source STEP and original GLB remain unchanged. `zup-display-provenance.json` records the source hashes, right-handed axis mapping and 0.025 mm seat offset; all geometry buffers are byte-identical. Adom Z now follows the original source Y, with the terminal floor at Z=0. This display pose is separate from a qualified native footprint model attachment.++An exact-solid OCCT measurement found the source model's five ordinary leads to be 0.35 mm long and its distinctive lead 0.45 mm long. The manufacturer drawing specifies minimums of 0.40 mm and 0.50 mm respectively. Rotation does not resolve this 0.05 mm discrepancy; the original geometry is preserved and is not certified against the drawing.
